    Description

    As high-throughput methods become more common, training undergraduates to analyze data must include having them generate informative summaries of large datasets. This flexible case study provides an opportunity for undergraduate students to become familiar with the capabilities of R programming in the context of high-throughput evolutionary data collected using macroarrays. The story line introduces a recent graduate hired at a biotech firm and tasked with analysis and visualization of changes in gene expression from 20,000 generations of the Lenski Lab’s Long-Term Evolution Experiment (LTEE). Our main character is not familiar with R and is guided by a coworker to learn about this platform. Initially this involves a step-by-step analysis of the small Iris dataset built into R which includes sepal and petal length of three species of irises. Practice calculating summary statistics and correlations, and making histograms and scatter plots, prepares the protagonist to perform similar analyses with the LTEE dataset. In the LTEE module, students analyze gene expression data from the long-term evolutionary experiments, developing their skills in manipulating and interpreting large scientific datasets through visualizations and statistical analysis. Prerequisite knowledge is basic statistics, the Central Dogma, and basic evolutionary principles. The Iris module provides hands-on experience using R programming to explore and visualize a simple dataset; it can be used independently as an introduction to R for biological data or skipped if students already have some experience with R. Both modules emphasize understanding the utility of R, rather than creation of original code. Pilot testing showed the case study was well-received by students and faculty, who described it as a clear introduction to R and appreciated the value of R for visualizing and analyzing large datasets.

    Description

    Data literacy is the ability to read, understand, work with, analyze, and argue with data. It is also the ability to derive meaningful information from data. Data literacy is not simply the ability to read text since it requires quantitative and analytical skills (for example: mathematical and statistical) involving reading and understanding data. Hence, with increased data literacy, one will be able to produce more insightful and evidence-based stories. This program has been localized to meet the local context of Thailand. EWMI-ODI and training team would like to express gratitude to the original program of World Bank’s Data Literacy Program, and advisors who supported the curriculum improvement for Thailand. This component will introduce basic concepts of data organization and cleaning as well as questions to help you evaluate the source of the data. It will also cover basic calculations and an introduction to statistics.

    Description
    1. Cleaning symbioses on coral reefs are mutually beneficial interactions between two individuals, in which a ‘cleaner’ removes and eats parasites from the surface of a ‘client’ fish. A suite of behavioural and morphological traits of cleaners signal cooperation with co-evolved species, thus protecting the cleaner from being eaten by otherwise predatory clients. However, it is unclear whether cooperation between cleaners and predatory clients is innate or learned, and therefore whether an introduced predator might consume, cooperate with, or alter the behaviour of cleaners.
    2. We explored the role of learning in cleaning symbioses by comparing the interactions of native cleaner fishes with both naïve and experienced, non-native and native fish predators. In so doing, we tested the vulnerability of the predominant cleaners on Atlantic coral reefs, cleaning gobies (Elacatinus spp.), to the recent introduction of a generalist predator, the Indo-Pacific red lionfish (Pterois volitans). 3...

    Maximum utilisations are expressed proportionally, by comparing the maximum half-hourly observed import power seen across the site's meter point(s), against the meter's maximum import capacity. Units for both measures are apparent power, in kilovolt amperes (kVA).

    To protect the identity of the sites, data points have been anonymised and only the site's voltage level information has been provided - and our estimation of the data centre type - has been provided.

    Methodological Approach

    Over 100 operational data centre sites (and at least 10 per voltage level) were identified through internal desktop exercises and corroboration with external sources.

    After identifying these sites, their addresses and their MPAN(s) (Meter Point Administration Number(s)) were identified using internal systems.

    Half-hourly smart meter import data were retrieved using internal systems. This included both half-hourly meter data, and static data (such as the MPAN's maximum import capacity and voltage group, the latter through the MPAN's Line Loss Factor Class Description). Half-hourly meter import data came in the form of active and reactive power, and the apparent power was calculated using the power triangle.

    In cases where there are numerous meter points for a given data centre site, the observed import powers across all relevant meter points are summed, and compared against the sum total of maximum import capacity for the meters.

    The maximum utilisation for each site was determined via the following equation (where S = Apparent Power in kilovolt amperes (kVA)):

    % Maximum Observed Utilisation =

     MAX(SUM( SMPAN Maximum Observed Demand))

     SUM( SMPAN Maximum Import Capacity)

    Quality Control Statement

    The dataset is primarily built upon customer smart meter data for connected customer sites within the UK Power Networks' licence areas.

    The smart meter data that is used is sourced from external providers. While UK Power Networks does not control the quality of this data directly, these data have been incorporated into our models with careful validation and alignment.

    Any missing or bad data has been addressed though robust data cleaning methods, such as omission.

    Assurance Statement

    The dataset is generated through a manual process, conducted by the Distribution System Operator's Regional Development Team.

    The dataset will be reviewed quarterly - both in terms of the operational data centre sites identified, their maximum observed demands and their maximum import capacities - to assess any changes and determine if updates of demand specific profiles are necessary.

    This process ensures that the dataset remains relevant and reflective of real-world data centre usage over time.

    There are sufficient data centre sites per voltage level to assure anonymity of data centre sites.

Description

Dirty Cafe Sales Dataset

Overview

The Dirty Cafe Sales dataset contains 10,000 rows of synthetic data representing sales transactions in a cafe. This dataset is intentionally "dirty," with missing values, inconsistent data, and errors introduced to provide a realistic scenario for data cleaning and exploratory data analysis (EDA). It can be used to practice cleaning techniques, data wrangling, and feature engineering.

File Information

  • File Name: dirty_cafe_sales.csv
  • Number of Rows: 10,000
  • Number of Columns: 8

Columns Description

Column NameDescriptionExample Values
Transaction IDA unique identifier for each transaction. Always present and unique.TXN_1234567
ItemThe name of the item purchased. May contain missing or invalid values (e.g., "ERROR").Coffee, Sandwich
QuantityThe quantity of the item purchased. May contain missing or invalid values.1, 3, UNKNOWN
Price Per UnitThe price of a single unit of the item. May contain missing or invalid values.2.00, 4.00
Total SpentThe total amount spent on the transaction. Calculated as Quantity * Price Per Unit.8.00, 12.00
Payment MethodThe method of payment used. May contain missing or invalid values (e.g., None, "UNKNOWN").Cash, Credit Card
LocationThe location where the transaction occurred. May contain missing or invalid values.In-store, Takeaway
Transaction DateThe date of the transaction. May contain missing or incorrect values.2023-01-01

Data Characteristics

  1. Missing Values:

    • Some columns (e.g., Item, Payment Method, Location) may contain missing values represented as None or empty cells.
  2. Invalid Values:

    • Some rows contain invalid entries like "ERROR" or "UNKNOWN" to simulate real-world data issues.
  3. Price Consistency:

    • Prices for menu items are consistent but may have missing or incorrect values introduced.

Menu Items

The dataset includes the following menu items with their respective price ranges:

ItemPrice($)
Coffee2
Tea1.5
Sandwich4
Salad5
Cake3
Cookie1
Smoothie4
Juice3

Use Cases

This dataset is suitable for: - Practicing data cleaning techniques such as handling missing values, removing duplicates, and correcting invalid entries. - Exploring EDA techniques like visualizations and summary statistics. - Performing feature engineering for machine learning workflows.

Cleaning Steps Suggestions

To clean this dataset, consider the following steps: 1. Handle Missing Values: - Fill missing numeric values with the median or mean. - Replace missing categorical values with the mode or "Unknown."

  1. Handle Invalid Values:

    • Replace invalid entries like "ERROR" and "UNKNOWN" with NaN or appropriate values.
  2. Date Consistency:

    • Ensure all dates are in a consistent format.
    • Fill missing dates with plausible values based on nearby records.
  3. Feature Engineering:

    • Create new columns, such as Day of the Week or Transaction Month, for further analysis.
